Product Description:

Technical Data
◆Number of poles:1,2,3,4,1+N,3+N
◆Nominal current In(A): 1,2,3,4,6,8,10,13,16,20,25,32,40,50,63
◇B The short-circuit release is to be set up to 3 In through 5 In.It serves especially for protection of circuits with such devices which do not cause any current surges(lights or socket circuits etc.)
◇C The short-circuit release is to be set up to 5 In through 10 In.It serves especially for protection of circuits with such devices which cause some current surges(groups of bulbs, motors etc.)
◇D The short-circuit release is to be set up to 10 In through 20 In. It serves especially for protection of circuits with devices which cause high current surges(transformers,double-pole motors,motors with heavy start etc.)
◆Nominal voltage:
◇1P (single-pole)~230/400V 50/60Hz
◇3P (three-pole)~400V 50/60Hz
◆Rupturing capacity:
◇EN60898-10,000A(nominal short-circuit and operational rupturing capacity)
◆Protection:IP40 for a sole MCB with its design, it protects against a hazardous finger or instrument touch as well as against very small foreign objects; It is without any protection against water leakage (water protection is to be solved with design of the switchboard casing)
◆Ambient temperatue: -5oC to +40oC pursuant to EN60898
◆Gauging temperature:+30oC pursuant to EN60898
◆Max.pre-inserted fuse:100AgG(>10kA)
◆Mechanical lifetime:≤20,000 cycles
◆Electrical lifetime:≤8,000 cycles
◆Fastening:By means of an unique snap mechanism(with arrestment in final positions)the carrying DIN strip EN50022,width 35mm, or even onto the falt surface by means of screws.
◆Removal form the DIN strip:
◇By means of an unique auxiliary snap mechanism, the MCB誷 can be removed even from a row of devices mutually interconnected by a forked or reed rack strip without necessity to dismantle the whole interconnecting strip.
◆Input terminals:
◇Clip terminals(with barrier layer), snap-locked against the worse input of a conductor
◇The input and output can be interchanged
◇They enable more conductors as well as interconnecting strips to be connected
◆Connect ability of conductors (Maximum cross-sections):
◇35mm2 solid conductor
◇25mm2 stranded conductor
◆Terminal protection:IP20
◆Tightening moment for terminals
◇2Nm(combined slotted-head screw)
◆Manufacture standard
◇EN60898,same to IEC 60898
◆Selectivity calss:3
◆Colored levers:
For better distinction among circuits in the switchboards,we supply also miniature circuit breaker with distinction of nominal currents by means of colored levers corresponding to the colors of turn fuses
◇8A(Light green)
◆Can be delivered also with only black levers

Q:The difference between the leakage switch of the air switch circuit breaker
Circuit breaker It is a switch function, but also to automatically protect the low-voltage distribution of electrical appliances. Its role is equivalent to the knife switch. Fuse. Thermal relay and other electrical components of the combination
Q:What is the difference between open air and circuit breakers?
The first two kinds of protection for the basic configuration of the air circuit breaker, the latter two for the optional function. So the air circuit breaker can also fault in the state (load short circuit, load over current, low voltage, etc.) cut off the electrical circuit
Q:Switch switch, disconnector, circuit breaker difference? What are the possible functions of each?
in the maintenance as a clear point, and can not carry sub-gate, or will pull the arc ACCIDENT.
Q:What is the solution of the leakage circuit breaker always jumping?
Do not let the lighting lines and socket lines mixed, so that the socket circuit leakage switch will open the leakage protection switch to trip .
Q:How to choose the home of the circuit breaker air switch?
Modern home electricity should be in accordance with the bright circuit, power outlet circuit
Q:Load switch, vacuum switch and circuit breaker
Vacuum switch: The contact seal acts in the vacuum container with the load switch
Q:What is the choice of low voltage electrical circuit breaker?
For example, a circuit breaker located outside the cockpit is temperature compensated so that its trip characteristics do not change with the temperature fluctuations common in flight.
Q:Is the MCB switch a circuit breaker or a component on the circuit breaker?
then if any branch of the circuit breaker circuit breaker circuit breaker will cut off the total circuit breaker All the power supply, if used in the branch circuit breaker will not affect the normal use of other branch electrical appliances
Q:Is there a circuit breaker in the circuit
And the fuse in the line failure, but to protect the fault of the line, but the problem appears here, assuming
Q:The difference between air switch and circuit breaker
The air circuit breaker is a switchgear with a variety of protection functions that can cut and turn on the circuit at rated voltage and rated operating current conditions.
